[FIX] web: BasicModel: discard changes when reloading

... from a new record.

Steps to reproduce the issue:
  - go to a multi-record view (e.g. list) of basically any model
  - click on 'Create' -> it opens a form view in edit mode
  - click on 'Discard' -> it goes back to the list
  - click on an existing record -> it should open the selected
    record in readonly.
However, it didn't display the data of the selected record, but
the default data of a new record (the result of a default_get).

This was because the changes weren't properly discarded when
reloading from a new record (it rather restored the record to its
initial state, i.e. to the result of the default_get).
